CONDITIONAL PROBABILITY OF INDEPENDENT EVENTS

P(x) = 0. 06 / 0. 40

P(x) = 0.15

Here is the table

Age group                         Brand X                     Brand Ytotal

a.Under 30 years old6%                              34%        40%

A’ (30 years and older)          9%                              51%         60%

Total                                      15%                               85%          100%

Probabilities are usually very sensitive to an information given as a condition. Sometimes, however, a probability does not change when the condition is supplied.  For other information related to the topic, click the link below
